In case someone needs some autumn color inspiration in their figures.

y = c(1,1,1,1,1)
x = c(1,2,3,4,5)
z = c(1,2,3,4,5)
df = tibble(x,y,z)

paletteplot = function(pp) {
df %>%
  ggplot(aes(x,y,color = factor(z))) +
  geom_point(size = 35) + 
  scale_color_manual(values = pp(5)) +
  theme_void() +
  theme(legend.position = "none") +
  coord_cartesian(xlim = c(0,6), ylim = c(1,1))
}
